To know oneself, one should assert oneself.

If you think you can do it, you can.

To be a good loser is to learn how to win.

You never know what motivates you.

By failing to prepare, you are preparing to fail.

If you've got a talent, protect it.

Know or listen to those who know.

Be gentle to all and stern with yourself.

The wise does at once what the fool does at last.
